About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-100
The AirTAC SAIJ80X300-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers robust thrust, providing 4523N of push force at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This model features a 300 mm nominal stroke that can be fine-tuned down by up to 100 mm, creating a usable travel window of 200-300 mm. It uses a SUS420J2 stainless steel rod for enhanced durability against moisture and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-100 Is Used
Product Changeover
Quickly dial in the 200-300 mm retract distance using the rear screw when adapting machinery to run different product sizes.
Commissioning Calibration
Fine-tune the end-of-stroke position during machine setup to achieve exact clamping or pressing depths without swapping cylinders.
Heavy Material Handling
Leverage the 4523N push force at 0.9 MPa to move heavy pallets or workpieces, relying on the adjustable stop to prevent overtravel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-100 the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial force—delivering 2513N push at 0.5 MPa—combined with variable end-stop positioning. If your setup needs less force, stepping down to a 63 mm bore yields 1559N at 0.5 MPa. Choose the SAIJ adjustable format over a fixed-stroke SAI when you need to dial in the exact retract position during commissioning or product changeovers without adding external stops.
Because the stroke is 300 mm, the M20x1.5 rod should be supported by an external guide to prevent excessive side-loading and premature seal wear. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series. This SKU supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-100 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm. This gives the 300 mm nominal stroke a usable travel window of 200-300 mm, enabling precise end-position tuning at commissioning without external stops.
Operating at 0.9 MPa, the SAIJ80X300-100 provides a push force of 4523N and a pull force of 3681N. At 0.5 MPa, it delivers 2513N push and 2268N pull.
